Filing an issue for this TODO: https://github.com/cockroachdb/cockroach/blob/d7135c364280b916ff1dd63b13c23a177c6e451c/pkg/sql/stats/stats_cache.go#L811-L812

Now that we've introduced merging of partial statistics, we should add one or more variables to disable it if necessary.

Jira issue: CRDB-23413

Reopening because it looks like we'd still produce merged statistics for existing partial stats.
